• Built agentic workflows and full automations with Claude Code and Google AI Studio.
• Also delivered AI-supported work in client engagements: used Claude Code for governance documentation, requirement drafts, and automations.

To achieve savings and optimize compliance, apps were restructured in line with the mappings in identity management, restrictions were defined and, above all, costs resulting from overuse were reduced. Communication with stakeholders, validation of authorizations with users and technical implementation in the SAP FI/CO and Sourcing & Procurement modules created significant added value for the group. This also included the corresponding documentation for the auditors.
